West Palm Beach Impact Windows & Doors

West Palm Beach Building Code Compliance

Our impact windows meet the coastal building standards required throughout West Palm Beach, ensuring your property is fully protected while maintaining compliance with WBDR requirements and historic district considerations.

Wind-Borne Debris Region (WBDR) Compliance

West Palm Beach falls within the Palm Beach County Wind-Borne Debris Region — but is NOT in the HVHZ. The ultimate design wind speed here is 167 mph (Risk Category II), with typical design pressures around ±50 psf in wall zones and ±75 psf at corners. Florida Product Approval is sufficient, giving homeowners a broader product selection at lower costs than HVHZ counties like Miami-Dade and Broward to the south.

Historic Districts & the Certificate of Appropriateness

El Cid, Flamingo Park, and Old Northwood are among West Palm Beach's more than a dozen locally designated historic districts (Grandview Heights and Mango Promenade also make the list), alongside more than 45 individually designated sites. The review step comes from the city's local designation under its preservation ordinance; National Register listing, which several districts also hold, is a separate and largely honorary recognition. Inside a district, any work that changes the exterior appearance requires a Certificate of Appropriateness, and the city grants historic approval before it issues the building permit. Staff approves minor work administratively, while larger projects go before the Historic Preservation Board; a matrix in the COA application shows which path applies. The city's district guidance favors repairing original wood windows and, where they are beyond repair, replacing in kind with aluminum impact products. Vinyl window frames are not permitted in the districts. We match period proportions, muntin patterns, and sightlines, and handle the COA alongside the permit.

Florida Building Code (FBC) Compliance

All our windows exceed statewide Florida Building Code requirements for structural integrity, energy efficiency, and safety performance, ensuring compatibility with Palm Beach County insurance requirements.

Intracoastal vs. Inland Wind Load Requirements

The design wind speed is one number citywide: 167 mph. What changes near the water is the engineering — Intracoastal-front sites are often assigned a more severe exposure category and corner-zone coefficients, which raise the required design pressure at the same map speed. Your permit drawings decide, not your neighborhood. You can check the design wind speed at your exact address with our wind-zone lookup.

Wind Load Requirements for Impact Doors

Doors face the same design-pressure requirements as windows, usually with bigger numbers, because they are the largest openings in the building envelope. A sliding glass door that fills the corner bay of an Intracoastal-facing living room sits in the harshest zone on the permit drawings, where required pressures run higher than the wall-zone figures. Impact doors are approved as complete assemblies, with frame, panels, hardware, and glazing tested together against the pressures your plans call out, typically around ±50 psf in wall zones and ±75 psf at corners here. Sliding glass doors and French doors both need a Florida Product Approval whose design-pressure rating meets those numbers, not just impact glass.

West Palm Beach Development Services Permitting

Building permits are filed through City of West Palm Beach Development Services. Fees are value-based, scaled to job value through the city's online Permit Planner portal, with no published flat fee schedule (fee structure verified June 2026). We price the permit into your quote, file the application, and coordinate with historic preservation where a COA applies. One wrinkle worth knowing: a West Palm Beach mailing address is not always City of West Palm Beach jurisdiction. Westgate and Belvedere Homes, for example, are unincorporated Palm Beach County, so their permits run through the county's Planning, Zoning & Building department (ePZB) on the county's own fee schedule; see our Palm Beach County page for how that works. The 30-second check: look up your address on the Palm Beach County Property Appraiser site and read the municipality field.

Armor Pro Windows holds Florida Certified Building Contractor license CBC1270699, and every installation we perform is permitted and inspected under the Florida Building Code.

Verify your specific address. Design wind speed and required certifications can vary even within a single county. Run a wind zone lookup for your address before specifying products or signing a contract.
